Portable head support
View Patent ↗The invention is directed to a portable head support designed to fit in the interior of a carry-on article carried by a passenger. The device provides head support for those who prefer sleeping in a face-down position and comprises a base and a head support connected along at least one of their abutting edges by a mechanism which permits the angle between the base and head support to be adjusted by the user.
1. An apparatus, comprising:
a baseboard comprising: a base;
at least one channel with a hinge located proximate to one end of the at least one channel; and
a headrest comprising:
at least one rail having a width substantially equal to the at least one channel that slidably engages the at least one channel;
a bracket disposed at an end of the at least one rail that limits movement of the headrest relative to the base in a first parallel direction by engaging the hinge when an edge of the headrest is proximately aligned with an edge of the base; and
a mechanical stop disposed on and having a substantially equal width as the at least one rail, wherein a surface of the stop is in contact with the channel when the headrest and base overlap, and wherein the mechanical stop engages a terminal edge of the channel when the headrest and base are non-overlapping.
2. The apparatus of claim 1 , wherein the base further comprises a side stop disposed on a side of the base, and the headrest further comprises a notch disposed on a side of the headrest, wherein movement of the headrest relative to the base in a second parallel direction is limited when the notch contacts the side stop.
3. The apparatus of claim 1 , wherein the headrest further comprises a removable cushion attached to the headrest using a detachable fastener.
4. The apparatus of claim 1 , wherein the headrest is detachable from the baseboard.
5. The apparatus of claim 1 , wherein the baseboard hinge permits the headrest to deploy to a principal angle in one degree of freedom.
6. The apparatus of claim 1 , wherein the baseboard hinge permits the headrest to deploy to a principal angle in greater than one degree of freedom.
7. A portable travel headrest system, comprising:
a headrest apparatus, comprising:
a baseboard comprising: a base
at least one channel with a hinge located proximate to one end of the at least one channel; and
a headrest comprising:
at least one rail having a width substantially equal to the at least one channel that nests within and slidably engages the at least one channel;
a bracket disposed at an end of the at least one rail that limits movement of the headrest relative to the base in a first parallel direction by engaging the hinge when an edge of the headrest is proximately aligned with an edge of the base; and
a mechanical stop disposed on and having a substantially equal width as the at least one rail, wherein a surface of the stop is in contact with the channel when the headrest and base overlap, and wherein the mechanical stop engages a terminal edge of the channel when the headrest and base are non-overlapping; and
a carry-on article adapted to accommodate the headrest, comprising:
at least one internal pocket comprising at least two reinforcing plates adapted to support the baseboard when the baseboard and headrest do not overlap.
